Is the household air conditioner, I here are generally only use in the summer, winter will not use?
It depends on you will maintain. I bought 94 orcs now still use air conditioning for 17 years, is working properly now, 20 years should be no problem. Outdoor parts is a bit rusty. Normal 10 years is no problem.
Winter best meets once every two months, electricity heating (compressor) twenty minutes before opening, according to the remote boot again! Once a half an hour! Air conditioning often period without compressor 'four-way valve will card cylinder, jam!
Design service life for twenty years! Because of the environment is different, generally in 10 years or so.
